Abstract
Abstract A drag mechanism for a spinning reel includes a first friction plate supported non-rotatably to the spool shaft and a second friction plate disposed adjacent to the first friction plate and supported non-rotatably to the reel body. An adjusting knob is screwed with the reel body, such that the adjusting knob is rotatable relative to the reel body. The range of rotation of the adjusting knob relative to the reel body is restricted. The adjusting knob includes a spring holder for holding a drag spring which is interposed between the first and second friction plates and an initial load adjuster. The initial load adjuster is movable toward or away from the friction plates to adjust an initial rotational resistance load applied against rotation of the spool shaft by the adjusting knob. The initial load adjuster also includes a display means for displaying an indication of the initial load set by the initial load adjuster.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
196 words
A drag mechanism for a spinning reel comprising a reel body, a spool and a spool shaft rotatable and movable longitudinally of said reel body, said drag mechanism for applying a resistance against rotation of said spool shaft and comprising: at least one first friction plate supported non-rotatably to said spool shaft, at least one second friction plate disposed adjacent to said first friction plate and supported non-rotatably to said reel body, an adjusting knob screwed with said reel body such that said adjusting knob is rotatable relative to said reel body, a drag spring, a restriction means for restricting a range of rotation of said adjusting knob with respect to said reel body, said adjusting knob including a spring holder for holding said drag spring, said drag spring being interposed between said first and second friction plates and an initial load adjuster, said initial load adjuster being movable toward or away from said friction plates to adjust an initial rotational resistance load applied against rotation of said spool shaft by said adjusting knob, said initial load adjuster including a display means for displaying an indication of said initial load set by said initial load adjuster.
Claim 2
Dependent Claim
196 words
A drag mechanism for a spinning reel comprising a reel body, a spool and a spool shaft rotatable and movable longitudinally of said reel body, said drag mechanism for applying a resistance against rotation of said spool shaft and comprising: at least one first friction plate supported non-rotatably to said spool shaft, at least one second friction plate disposed adjacent to said first friction plate and supported non-rotatably to said reel body, an adjusting knob screwed with said reel body such that said adjusting knob is rotatable relative to said reel body, a drag spring, a restriction means for restricting a range of rotation of said adjusting knob with respect to said reel body, said adjusting knob including a spring holder for holding said drag spring, said drag spring being interposed between said first and second friction plates and an initial load adjuster, said initial load adjuster being movable toward or away from said friction plates to adjust an initial rotational resistance load applied against rotation of said spool shaft by said adjusting knob, said initial load adjuster including a display means for displaying an indication of said initial load set by said initial load adjuster.
Claim 3
Dependent Claim
47 words
A drag mechanism according to claim 1, wherein said initial load adjuster is supported to said adjusting knob by a screw means such that said initial load adjuster is movable toward or away from said friction plates independently of a rotational adjustment position of said adjusting knob.
Claim 4
Dependent Claim
49 words
A drag mechanism according to claim 1, wherein said initial load adjuster is supported to said adjusting knob by use of a cam means such that said initial load adjuster is movable toward or away from said friction plates independently of a rotational adjustment position of said adjusting knob.
Claim 5
Dependent Claim
198 words
A drag mechanism for a spinning reel comprising a reel body, a spool and a spool shaft rotatable and movable longitudinally of said reel body, said drag mechanism for applying a resistance against rotation of said spool shaft and comprising: at least one first friction plate supported non-rotatably to said spool shaft, at least one second friction plate disposed adjacent to said first friction plate and supported non-rotatably to said reel body, an adjusting knob screwed with said reel body such that said adjusting knob is rotatable relative to said reel body, a drag spring, a restriction means for restricting a range of rotation of said adjusting knob with respect to said reel body, said adjusting knob including a spring holder for holding said drag spring, and an initial load adjuster, said initial load adjuster being movable toward or away from said friction plates to adjust an initial rotational resistance load applied against rotation of said spool shaft by said adjusting knob, said initial load adjuster including a display means for displaying an indication of said initial load set by said initial load adjuster, said display means being disposed between said initial load adjuster and said adjusting knob.
Claim 6
Dependent Claim
198 words
A drag mechanism for a spinning reel comprising a reel body, a spool and a spool shaft rotatable and movable longitudinally of said reel body, said drag mechanism for applying a resistance against rotation of said spool shaft and comprising: at least one first friction plate supported non-rotatably to said spool shaft, at least one second friction plate disposed adjacent to said first friction plate and supported non-rotatably to said reel body, an adjusting knob screwed with said reel body such that said adjusting knob is rotatable relative to said reel body, a drag spring, a restriction means for restricting a range of rotation of said adjusting knob with respect to said reel body, said adjusting knob including a spring holder for holding said drag spring, and an initial load adjuster, said initial load adjuster being movable toward or away from said friction plates to adjust an initial rotational resistance load applied against rotation of said spool shaft by said adjusting knob, said initial load adjuster including a display means for displaying an indication of said initial load set by said initial load adjuster, said display means being disposed between said initial load adjuster and said adjusting knob.
Claim 7
Dependent Claim
30 words
A drag mechanism according to claim 1, wherein between said adjusting knob and said reel body is provided a display means for displaying an adjusting position of said adjusting knob.
Claim 8
Dependent Claim
31 words
A drag mechanism according to claim 4, wherein between said adjusting knob and said reel body is provided a second display means for displaying an adjusting position of said adjusting knob.
